New Advances In Aerobic Granular Sludge Technology Using Continuous Flow Reactors: Engineering And Microbiological Aspects
Abstract
Aerobic granular sludge (AGS) comprises an aggregation of microbial cells in a tridimen sional matrix, which is able to remove carbon, nitrogen and phosphorous as well as other pollutants in a single bioreactor under the same operational conditions. During the past decades, the feasibility of implementing AGS in wastewater treatment plants (WWTPs) for treating sewage using fundament tally sequential batch reactors (SBRs) has been studied. However, granular sludge technology using SBRs has several disadvantages. For instance, it can present certain drawbacks for the treatment of high flow rates; furthermore, the quantity of retained biomass is limited by volume exchange.
Therefore, the development of continuous flow reactors (CFRs) has come to be regarded as a more competitive option. This is why numerous investigations have been undertaken in recent years in search of different designs of CFR systems that would enable the effective treatment of urban and industrial wastewater, keeping the stability of granular biomass. However, despite these efforts, satisfactory results have yet to be achieved. Consequently, it remains necessary to carry out new technical approaches that would provide more effective and efficient AGS-CFR systems. In particular, it is imperative to develop continuous flow granular systems that can both retain granular biomass and efficiently treat wastewater, obviously with low construction, maintenance and exploitation cost. In this review, we collect the most recent information on different technological approaches aimed at establishing AGS-CFR systems, making possible their upscaling to real plant conditions. We discuss the advantages and disadvantages of these proposals and suggest future trends in the application of aerobic granular systems. Accordingly, we analyze the most significant technical and biological implications of this innovative technology.

Process Design Engineering
PROCESS ENGINEERING AND THE ROLE OF PROCESS ENGINEER
Process design is the design of processes for desired physical and or chemical transformation of materials. Process design is central to chemical engineering and it can be considered to be the summit of chemical engineering, bringing together all of the components of that field. Process Engineering involves the design of unit operations & equipment design.
Role of Process Engineer: Chemical engineers (or process engineers) are responsible for developing new industrial processes and designing new process plants and equipment or modifying existing ones. The processes that they come up with are used to create products ranging from oil and gas, chemicals, petrochemicals, and specialty chemicals to food and drink. It is a vocation wherein the process engineer is supposed to perform any one or all of the activities mentioned below to provide documentation for a safe, reliable, and profitable design
Design new equipment/unit/plant as per good and internationally accepted engineering practices (Greenfield)
Rate or checks the adequacy of existing equipment/unit/plant for changed operating conditions (e.g. pressure, temperature, flow, etc.) as per good and internationally accepted engineering practices (Brownfield)

Engineering and Design- Design Of Small Water Systems
Introduction:
This manual provides guidance and criteria for the design of small water supply, treatment, and distribution systems. For the purpose of this manual, small water systems shall be those having average daily design flow rates of 380 000 liters per day (l/d) (100 000 gallons per day (gpd)) or less. However, the use of the term small is arbitrary, there being no consensus in the water supply literature with respect to its meaning. Regulations regarding the acceptability of a water source, degree of treatment required, and the monitoring requirements are not based on flow rates, but rather on a water system classification relating to the number of people served and for what period of time. Figure 1-1 provides a flowchart for system classification. Refer to Chapter 3, paragraph 3-4b for the appropriate nomenclature.

Engineering Design of a Disposable Water Bottle for an Australian Market
Abstract:
The primary purpose of this project is to investigate the engineering design process and use it to design a disposable water bottle for mass production that is aesthetically pleasing, structurally sound, market appropriate and financially viable. It is the intention that the water bottle, complete with branding, will go on sale in the Australian market. In the past decade bottled water has grown to become a major seller in the Australian beverage market. With many resources spent on the marketing and sales of a disposable water bottle, this project endeavor's to design a bottle tailored to its target demographic from the ground up. Largely in depth survey research from select focus groups within a target demographic will assure the accuracy of the specifications and the direct relevance to the intended consumer. An engineering design approach ensures that the bottle will not only be rigorously designed to heavily researched specifications but also computationally tested to guarantee the success of the completed product.

Wastewater Engineering In Questions And Answer
In Palestine, the existing water and wastewater/sanitation infrastructure suffers from inadequate level of skills in planning, designing, managing, operating and maintaining of the infrastructure to ensure its sustainability. Furthermore, there is no coordinated effort on human resources development aimed to build the needed managerial and technical capacity among water and wastewater service providers. So far, this sector lacks any needs-based capacity building and systematic training arrangements.
